Abstract
Blocks with a casing composed of upper and lower parts are produced by inserting the upper and lower parts in an inserting device above and below pushing elements between upper and lower pressing dies of a press, displacing by the pushing elements the lower part in a chamber of a mold towards the lower pressing die and the upper part towards the upper pressing die with self-releasable holding on the latter, withdrawing the inserting device from a pressing region between the upper and lower pressing dies, and cyclically repeating these steps in synchronism with a working stroke of the press.
